A friend loaned me his Sigma 50-500 lens and his tripod to have a play with. So I went out into the back garden, set it all up and shot some local wildlife. :D

The above was taken at 500mm, 400 ISO, 1/350 at f5.6. I find the results slightly soft. Not sure if it's the focus or a less than perfectly solid tripod (the plates were slightly wobbly) or just the nature of the beast. What's interesting, though, is that I threw my 1.4x TC (Kenko) on it and the results were nearly the same quality as without. And that's with manually focussing.
But the 50-500 is a beast (for me) at 1850g. I know if I owned it I would probably drop it on more than one occassion. I really like the reach - effectively 800mm without a TC and 1120 with the 1.4x! Oh well, back to the drawing board.
